ESP32 Vibration-Meter PCB Design
Budget: ₹1,500 – ₹12,500 INR
I’m moving my ADXL1005 breadboard setup to a production-ready board. The goal is a compact, low-noise PCB that feeds the accelerometer’s analog signal through proper conditioning into an ADS8685 16-bit 500 kSPS ADC and then over SPI to an ESP32 module. From there the ESP32 will stream data via Wi-Fi, giving the project full IOT capability exactly as requested.
Beyond the core signal chain, I’d like space for a temperature sensor and “vibretion” add-ons so environmental and supplemental vibration data can ride in the same packet. Clean power, solid grounding and careful separation of the high-speed digital and sensitive analog sections are mandatory to avoid aliasing or RF self-interference.
Deliverables
• Complete schematic (KiCad, Altium, or Eagle).
• Four-layer PCB layout with Gerbers, drill files and pick-and-place.
• BOM with manufacturer part numbers and at least one supplier quote.
• Short design report explaining the ADC front-end, power tree and Wi-Fi antenna keep-out.
I’ll review the schematic first, then the layout, with one revision cycle at each stage. Please confirm experience with fast-sampling mixed-signal designs around the ESP32 and comfort meeting good Wi-Fi layout practice.
